Title: Current transformer device of error compensation type
Inventor: KITAGAWA HIDEO
IPC: H01F27/42
Filed: 1989-12-25
Abstract: PURPOSE:To reduce an influence of a secondary impedance and to eliminate a need for an auxiliary current transformer, a tertial winding and a toroidal core by a method wherein an output voltage of an operational amplifier is applied to a terminal of a secondary winding and it is adjusted by using a specific circuit structure. CONSTITUTION:Since an output voltage V0 of an operational amplifier 2 is applied to the other end of a secondary winding 1b, a voltage-dividing ratio of impedance circuits 10, 11 is adjusted according to a secondary impedance, the output voltage V0 of the operational amplifier 2 is adjusted and an error can be compensated. When the error is compensated excessively, a magnetic flux is generated inside an iron core of a current transformer 1 by an excess voltage. Since an excitation impedance is connected in series, a secondary current is suppressed and the amplifier is operated stably. Consequently, even when an amplification factor of the operational amplifier 2 is set erroneously, an influence of the secondary impedance can be reduced. Thereby, it is possible to obtain a current transformer device which is operated surely against a half- wave rectification waveform, which is small-sized and whose cost is low.

Title: Diaphragm and acceleration sensor
Inventor: KAWAKAMI TAKAHIRO
IPC: G01L7/08
Filed: 1993-12-28
Abstract: PURPOSE:To prevent the formation of bubbles in a fluid inside a case by forming waveforms from the central part of a diaphragm plate over to the peripheral part thereof and by making a wave height and a pitch larger toward the central part. CONSTITUTION:Silicone oil 16 damping deflection of an acceleration detecting element 15 is sealed in a case 11. When the silicone oil 16 expands or contracts due to a change in temperature, the shape of a diaphragm 11a changes, the capacity of the case 11 changes and absorbs the change in the volume of the oil 16 and thereby occurrence of a disadvantage due to the change in the volume is prevented. In other words, only the shape of the diaphragm 11a changes due to the expansion or contraction of the oil 16 caused by the change in temperature. Since no sponge is used, gas is not produced and no bubble is formed in the oil 16. Accordingly, the output characteristic of the acceleration detecting element 15 is not varied and thus acceleration can be detected accurately.
